Beaufortia is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to Southwest Australia. The genus Beaufortia is closely related to Melaleuca, Calothamnus, Regelia and several others, differing mainly in the way the anthers are attached to the stalks of the stamens, and in the way they open to release their pollen. Beaufortia anthers are attached at one end and open by splitting at the other. Description Plants in the genus Beaufortia, sometimes commonly known as bottlebrush are evergreen shrubs with very small, glandular, aromatic leaves usually oppositely arranged. The tallest are up to in height. Most are andromonoecious, meaning they have both male and bisexual flowers on one plant. The flowers are in spikelike or headlike inflorescences. The flower has five triangular sepals and five white, yellow, red, pink, or purple petals, which are sometimes hairy. The petals usually fall off as the flower opens, or shortly after that. The stamens are red or deep pink, arranged in five bundles and extend well beyond the petals, giving the inflorescence its colour. Unlike other closely related genera such as Melaleuca, the anthers are attached to the filament at their base and release their pollen through two curved slits on the other end. Flowering in most species occurs throughout the year but mostly between late spring and autumn. The fruit is a dehiscent capsule with three valves, each holding a winged seed.<ref name=FloraBase>{{FloraBase|name = Beaufortia’'|id =21813}}</ref> Taxonomy and naming The first formal description of the genus Beaufortia was published in 1812 by Robert Brown in William Aiton's Hortus Kewensis. It was followed by a description of the first-named species, Beaufortia decussata. The genus was named for the English gardener and botanist Mary Somerset, Duchess of Beaufort. In Curtis's Botanical Magazine it is noted that "her grace possessed a flourishing botanical garden at her seat, at Badminton, in Gloucestershire". Some taxonomists have suggested that Beaufortia along with Calothamnus, Conothamnus, Eremaea, Lamarchea, Petraeomyrtus, Phymatocarpus and Regelia should be included in the genus Melaleuca but the change has not been adopted by most herbaria. Distribution and habitat All species of Beaufortia occur in the South West Botanical Province and about half the species also occur in the Eremaean province. Beaufortias are often found in sand plain and in heath, although Beaufortia sparsa usually grows in marshy places and is known by the common name swamp bottlebrush. Ecology Most
